AUTOMOBILE-HORN.

Application filed April 5, 1916.

To all whom it may concern.'

Be it known that l, Josnrr-r J. HEEL- nAUnn, aA citizen of the United States, residing at Richmond Hill, county of Queens, State of New York, have invented a certain new and useful Improvement in Automobile-Horns, of which the following is a full, clear, and exact description.

My invention relates to improvements in automobile horns and has for its object to produce a horn which is durable, simple in construction and easy to manufacture. It further has for its object to produce a horn in which the disk-operating parts are all mounted on and carried by the rear member of the horn. It further has for its object to provide a horn in which the casing, while it supports the diaphragm, does not have to be provided with a projecting ange for the purpose of holding the diaphragm. It further has` for its object to provide a horn with universal clamping means. It further has for its object to provide novel means for centering the diaphragm upon the casing. It further has for its object to produce a horn in which the projections on the face of the agitating member are stamped out and formed upon a press, the projections having the general shape of exposed por'- tions of embedded balls. It further has for its object to provide a simple and efficient means whereby sections of pinion wires may be firmly secured to the parts driven by the pinions formed therefrom.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which- Figure l is a front elevation of a horn embodying my invention with the front portion and diaphragm removed;

Fig. 9 is a side 'View of one of the pinion sections before assembling.

Referring more particularly to the drawings, in my horn there is a cup-shaped rear member 1, upon which is mounted a gear wheel 2 whose revolving spindle or shaft 3 passes through the rear member l. To this shaft is connected the actuating means et.. This actuating means can be moved in either direction to operate the horn. It is provided with a spring 5 which normally tends to retract it to a normal intermediate position, from which it can be moved in either di reotion to actuate the horn. 4i is the handle of the actuating member, which in the form shown in Fig. l is long enough to extend to the dash when the horn is located within the hood. It is connected to the actuating member by a universal joint 4t2 so that it can be used when at an angle to the shaft.

Mounted upon the inside of the base is ay spring 6 which bears upon the inner end of the spindle 3 which carries the iirst driving gear. This presses the driving gear toward the rear of the case so as to take up any lost motion and prevent rattling. Mountedupon a Xed second spindle is a gear-wheel 7 and a pinion 8 which meshes with the first gear 2; and mounted upon a third and fixed spindle 7 is the agitating device 9, which is also provided with a pinion having teeth l0, said pinion meshing with the second gear wheel 7 The pinions of these two members are made from pinion wire, which is cut off in suitable lengths, the front portions being slightly turned down so as to produce shoulders l0 thereon as shown in Fig. 9. The members 7, 14 and 10 are provided with holes l1 and internally projecting lugs ll, which enter one or more of the grooves between the ribs 102 in the reduced portion o-f the cut off pinion wire section so as to prevent relative rotation of the pinion and its member. The forward portions of the projections upon the pinion member are swaged down as at l2 so as to clamp the pinion securely to its member.

The spindle 7 is provided with a head and has its end screw-threaded. It is screwed into a threaded hole in the rear member. To its projecting end a lock nut 72 is applied. The spindle for the gear 7 is similar to the spindle 7 except that it is shorter.

The agitating member 9 is backed by one device the pinion member 10 extends through both the portions 16 and 9 and its projections are swaged down to hold them together. These parts, after this sWaging, are then case-hardened so as to produce hard agitating surfaces as Well as a durable pinion. The agitating surfaces 14, asthe agi.- tator is revolved, pass a point which is con` centric With the casing. Uponithe forward edge of the rear member is mounted a diaphragm 17 having' at its center a boss 1S through which passes a screw 18 held by,V aI

lock nut and provided with a hardenedV poi nt Whichl is engaged by the several agitating surfaces 14 as they passbeneathit: The

diaphragm 17 is provided with projections 19, 19 which engage the face member 20- andthe rear member 1 and act to center itV Within the casing. phragm is located the'front portion of the casing 20, to which the horn 21 is connected. The front and rear sections of the'casing Vare provided With holes 22, whichv register With holes 23 in the diaphragm and through these holes are passedy screws or bolts 24 which. hold the front and rear members together, clamping the diaphragm between them so.l that the' diaphragm. is securely held iny po sition Without the use ofany protecting flanges upon the casing membersI The holes 23 in the diaphragm are larger than the securing screws 24 sothat the securing screws Vdo not interfere With the vibration ofthe disk.

25 is a supporting bracket, riveted' toga peripheral portion of the case andas engaged by the; lower end' of the diaphragm 17, thusassisting in the centering ofthe diaphragm Within the case. It ,1s-providedr with Vsecurf ing bolts 2G-svhich are located" at the angles` of square. These securing means serve-'tol hold clamps 27 Which, on account of thelocation of the securing means 26, cani be placed.4 so as toA have their axes'in linewitlrV the axis of the horn or at-right angleSthere to Without' changing the bracket.

In order toprevent the 'actuating memberV 4 andthe first gear Wheel 2 fromcoming into= close engagement With thev sides of the back member, I2 prov-ide Washer 28Which is of slightly greater thickness than the thicknessv of the back! of thefcasing; Throughv this- Washer 2S,` as Well as throughthe actuating: memberl 4=and the gear- 2,. the spindle, which3 In fi'ontof the dia-v is a. square rivet, passes. The upsetting ofV theends of this rivet holds the parts all together, While the Washer referred to' prevents the actu-ating member and the gear from being drawn so closely together as to bindy upon the base. The Washer has a round hole. It is case-hardened so as to present' a: durable Wearing surface.

In the modification shown in Figs. 5 and 6, the actuating member is provided With a handle 30 rigidly fixed thereto as is desirable When the horn is to be mounted near the drivers seat or upona motor cycle.

As Will be evident to- `those skilled in the art, my invention permits of various modiications Without departing from the spirit thereof or the Vscope ofthe appended claims;

I claim:

Inean automobile horn, the combination of a. cup-shapedy containing member composed of al bottom; and affiangeless circular Wall perpendicular thereto, agitating` means contained therein and surrounded by saidv perpendicular Wall, a. cupped face member, securing devices passing through. the bottoms of said containing member andof said face4 member, a diaphragm clainpedrbetiveen opposing surfaces onA said members, the poi'- tions ofthe members presentingsaidy opposing surfacesV and the periphery of saidY dia-` phragm being in line With the body of said j for securing said cup-shaped member andy said face member together, said securing means passing vWithin the inner Walls of said tivo membersand engaging the face of one and the bottom of the other, said diaphragm having centering projections located WithinI and engaging the Wallsof said Cupshaped member- 3. In. an automobile horn, the combination of a cup-shaped member, a face member, a diaphragm lyingk between said tvvo; members, means contained' iny said cup-shapedk member for agitating saidwdiaphragimand'means for securing saidk cup-shaped Vmember yand said face member togethensaid securing means passing Within' the: inner Walls of saidy two members said diaphragmf yhaving. centering projections located.'
